Claims.

This inv ion relates, generally, to certain improvements in typographica machines and, sore particularly to 33 mechanism of these machines for transferring the assembled line of 5 ma :ices, after casting or" the line of type, to the position for distribution into their individual boxes or magazine. I

To effect this transfer of the matrices, two suspending bars for the matrices, known as the second elevator bar and the distributor box bar", each formed to receive the matrices, which are slid on to and on" from the bars by the mech anism oi the typographical, machine, which is well understood in this art and will not be described here, as this invention to do only with the construction of these bars.

The object of this invention is to provide an improved interlocking construction for the abutting ends of the aforesaid second elevator bar and distributor box bar whereby an exact and accurate aiinernent is assured, providing a smooth and easy transfer of thematrioes from one barto the other sliding the same longitudinally on the. bars and preventing undue wear ordamage to the ends of said. bars, by means of the novel features of construction which will be more fully described and illustrated the accompanying drawing. '1'th drawing, like parts in the several views have been given the same reference numeral.

Fig. 1 is a side elevationoi a second'el'evator bar and distributor box bar in alined position; Fig. 2 is an enlarged end View of the second elevator bar; Fig. 3 is an enlarged bottom plan View of the ends of the two bars as the same are being brought into alined position shown in Fig. 1. One of the bars upon which the matrices are slid, longitudinally, is known asthe second eleva- This bar is carriedator bar and is shown at 1. and operated by an arm (not shown) forming a part of the mechanism of a typographical machine, in the manner well understood in connection with these machines.

The top or rectangular part la, 12;, etc., of this bar is formed for pivotal attachment by means i of which the bar is suspended from said arm and thereby raised after receiving the matrices, and brought into alinement with the distributor bar 2, as shown in Fig. 1.

The matrices are not shown in the drawing, as the same are of the usual construction, which is well understood, and are suspended from the under-cut grooves 3, 3a, etc., in the V-shaped lower portion of each of said bars, being slidable longitudinally and transferred from one bar to 55 the other, when the same are in alinement by the mechanism of the typographical machine referred to.

These bars are usually constructed of a semisoft steel to avoid excessive wear of the matrices, and if the grooves (3, 3a, 3b, etc.) are not smooth, or become distorted by impact of one end against the other duringthe transverse movement into alinement, the matrices become jammed or wedged and do not slide freely from one bar to the other and the principal object of this invention is to provide an interlocking joint by so constructing the abutting ends of the bars as to avoid actual contact of the end edges of the grooves until the bars have reached their alined position, as shown in Fig. 1, thus eliminating the chance of damage which is caused by engagement and impact of the aforesaid end edges of the grooves, due to a slight lost motion or wear of the supporting bearings, etc., which permits even a small endwise or longitudinal displacement of one of the bars, usually the second elevat-or bar 1, which, as stated, is pivotally suspended upon the end of an operating arm which raises it from its lower position, with the matrices suspended thereon to its upper position in alinement with the distributor bar 2. A further im portant feature provided by the construction which is herein described is found in the relatively substantial construction of projecting portions of the end of the bar which prevents breakage of the same in use or handling.

The ends of the bars which will abut each other when the bars are brought into alinement are formed with a number of complementary steps or set-back portions with the vertical or abutting walls at an oblique angle transverse to the longitudinal axis or vertical plane of the bars These angular Walls are shown at 4, 5 and 6, in Figs. 2 and 3, for the bar 1 and corresponding complementary angular walls at 7, 8 and 9 for the bar 2.

As shown in Fig. 3, in bottom plan view,the bar 1, illustrating the second elevator bar, is moved by the arm from which it is suspended, heretofore referred to, in a transverse or sidewise motion in parallelism with the distributor bar 2, and during the last part of its travel its end moves, as indicated by the dot-and-dash lines, into engagement with the adjacent end of the distributor bar 2. As will be seen by reference to Fig. 3, the complementary angular faces of the several steps at the ends of the bars 1 and 2, heretofore described, do not come into actual contact until the bar 1 reaches its alined position with the bar 2, thus avoiding injury to the adjacent end edges of the grooves, which would be caused with the usual square end construction, by the hitting of one against the other if the moving bar 1 should be even slightly displaced, due to wear of the supporting bearings and parts, etc.

The multiple step or set-back construction for the ends of the bars also has a further advantage and utility in facilitating the smooth and uninterrupted travel of the matrices as the same are slid from the second elevator bar 1 to the distributor bar 2, as the matrices first slide over the abutting faces 47 .of the said bars, thus partially passing from the first to the second bar, and, in a like manner, successively passing the abutting faces 58 and 69. 7

It will be noted that the steps or set-back portions on the two bars are constructed and arranged with the outer faces 4-7 extending over the ends of four grooves, while the other faces, 58 and 6-9, each extend over two grooves. This constructionand arrangement was determined as the result of a number of experiments and is for the purpose of providing additional strength for the outer projecting portion Zat the point of the V-shaped lower portion-of the bar 2, which portion has a relatively small crosssectional dimension on account of its location and, consequently, is more liable to injury or breakage, both in operation and handling.

The provision of three steps has also been determined as preferable with the standard seven groove bars. A similar construction with seven steps, one for each groove, failed to provide the necessary .and desirable strength for the outer or lower projection (at the point of the V-shaped portion) and, furthermore, the small size of the individual steps arenot as readily formed with the exactness required in practical working. Two steps might be used with substantially the same advantages as three steps but, as stated, three steps were found to provide the best results from the standpoint of strength of parts, avoiding injury or breakage, and providing for the smooth, uninterrupted passage of the matrices over the abutting ends of the bars, all of which are important and very practical advantages in the machines.

'What I claim as new and desire to secure by Letters Patent is:-
